Title: Low activity nuclear density gauge
Inventor: DEP W LINUS
IPC: G01T1/36
Filed: 2003-01-09
Abstract: A nuclear density gauge and test method is provided for measuring density material in a relatively thin zone beneath a surface of the material. The gauge comprises a gauge housing and a substantially planar base on said gauge housing adapted to be positioned on a surface of the material sample. A gamma radiation source having a characteristic primary energy and an activity of no more than 100 microcurie is mounted within the housing and cooperates with the base for emitting gamma radiation through the base and into an underlying material sample.  An energy selective gamma radiation detector is mounted within the gauge housing and in laterally spaced apart relation from the gamma radiation source. The gamma radiation detector is operable for quantifying the energy level of the detected gamma radiation. Shielding is provided within the gauge housing between the source and the detector for preventing gamma radiation from passing directly from said source to the detector. An analyzer is connected to the detector for detecting gamma radiation counts in a predetermined energy spectrum having a lower limit of 0.1 MeV or greater and an upper limit which is less than the characteristic primary energy of said source. The density of the sample is calculated based upon the gamma radiation counts obtainedby the analyzer within the predetermined energy spectrum.

Title: Low-emissions diesel fuel blend
Inventor: VALENTINE JAMES M
IPC: C10L1/02
Filed: 2001-08-01
Abstract: A low-emissions diesel fuel comprises a catalyzed blend of fatty acid esters , preferably derived from soybean oil and/or tallow and aviation kerosene. The  catalyzed blend is effective in lowering regulated emission pollutants, amon g which are NOx, particulates, hydrocarbons and carbon monoxide. The catalyst will comprise fuel-soluble platinum and/or cerium or iron. The cerium or iro n are typically employed at concentrations of from 2 to 25 ppm and the platinu m from 0.05 to 2 ppm, with preferred levels of cerium of iron being from 5 to 10 ppm, e.g., 7.5 ppm, and the platinum being employed at a level of from 0.1 t o 0.5 ppm, e.g., 0.15 ppm. A preferred ratio of cerium and/or iron to platinum  is from 75:1 to 10:1. The jet fuel component will typically be employed at a  volume ratio to the fatty acid esters of from about 2:1 to about 5:1, e.g., about 4:1. The full range of blends extends from 50:1 to 1:50 with some benefit. The jet fuel component of the blend preferably contains grade 55, 5 0- 300 ppm detergent, 25 to about 500 ppm lubricity additive and 0.1 - 1 ppm platinum COD and 5-20 ppm cerium oleate or octoate. In addition to the fuel blend, a method is provided for reducing the emissions of pollutants from a diesel engine, comprising running the engine on a fuel as defined.

Inventor: STUMPF MICHAEL
IPC: G01M3/24
Filed: 2003-03-25
Abstract: An improved and non-destructive test apparatus utilises ultrasound wave energy to automatically judge the sealing effectiveness of a sealed compartment (30) such as the cabin of a motor vehicle or aircraft. An ultrasonic transmitter (28) generates ultrasound energy of a specified frequency within the compartment (30), and one or more ultrasound sensors (20) outside the compartment (30) detect the presence and amplitude of ultrasound energy at the specified frequency. The detected energy level is compared to a calibrated threshold (84), and a leak indication is generated if the threshold is exceeded (42, 52). In a factory setting, the compartment (30) can be passed through an arched array of ultrasound sensors (18, 20) strategically located to detect the presence and amplitude of ultrasound energy of the specified frequency in the vicinity of potential leakage areas of the compartment (30). If the position of the compartment (30) relative to the sensor array is known, the leak indication can be used to pinpoint the location of the leak, and to suggest specific corrective action (52).

Title: Isocitrate dehydrogenase, gene thereof, and use of the same in the treatment of obesity, hyperlipidemia, and fatty liver in lipid biosynthesis
Inventor: JUNG UN-JU
IPC: C12N15/63
Filed: 2001-07-26
Abstract: The present invention relates to a cytosolic isocitrate dehydrogenase, its gene, and its use in the treatment of obesity, hyperlipidemia, and fatty liver. The expression of the IDPc gene and the concomitant increase in IDPc level bring about an increase in the cellular level of NADPH, which causes the lipid deposition in adipocytes, leading to obesity and fatty liver. A decrease in the cellular level of NADPH, resulting from the suppression of the gene expression of IDPc, has the effect of inhibiting the lipid deposition in adipocytes. Further, by taking advantage of the suppressive or inhibitory effects of isocitrate dehydrogenase inhibitors, pharmaceutically effective materials for the prophylaxis and treatment of obesity, hyperlipidemia and fatty liver can be developed.

Title: System and method for training in military operations in urban terrain
Inventor: RIPINGILL ALLEN E JR
IPC: F41G3/26
Filed: 2001-11-15
Abstract: A stationary area weapon effects simulator is mounted to the ceiling of a room in a building being assaulted by soldiers equipped with optical detectors and small arms weapons having small arms transmitters (SATs). Area effects weapon codes simulating the detonation of a grenade, bomb, artillery shell or chemical/biological weapon are encoded onto infrared signals emitted by a plurality of LEDs in the weapon effects simulator and these codes are logged in player units (DPCUs) carried by the soldiers. The simulated area weapon effects may be confined to particular angular zones and this zone information may also be encoded onto the infrared emissions. An alternate embodiment utilizes a stationary locator in a room which only remits infrared signals with location information encoded in the same which are logged by the player unit. Area weapon effects and location information may be downloaded from the player units, along with conventional casualty, near miss and time of occurrence data for assessment of tactics and weapons usage accuracy during after action review (AAR) by an instructor. A red rotating beacon may be added to the area weapon effects simulator to indicate the simulated detonation and/or to indicate that a structure such as a bridge has been blown up and ca no longer be used. The area weapon effects simulator can be activated by sending an RF command received through a pager, or by manual devices such as an electro-mechanical switch connected to a trip wire.
